Understanding the Relationship

* Avogadro's Number: One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.). This is known as Avogadro's number.

Calculation

1. Set up the conversion factor:

(1 mole Si / 6.022 x 10^23 atoms Si)

2. Multiply the given number of atoms by the conversion factor:

3.01 x 10^23 atoms Si * (1 mole Si / 6.022 x 10^23 atoms Si)

3. Cancel out the units of "atoms Si" and perform the calculation:

(3.01 / 6.022) moles Si = 0.5 moles Si

Answer: 3.01 x 10^23 atoms of silicon is equal to 0.5 moles of silicon.
